Metro Waste Reclamation District is one of the largest wastewater treatment plants between the Mississippi River and the west coast. Treated water is discharged into the South Platte River, and contributes 90% of the river’s annual flow at the point of discharge.
Howard County, Maryland, Bureau of Utilities recently completed the $92-million Addition No. 7 project at the Little Patuxent Water Reclamation Plant (LPWRP) to improve the quality of the plant’s effluent discharge and to reduce harmful nutrients reaching Chesapeake Bay. The project’s various increments took over five years to complete and incorporated innovative design solutions and state-of-the-art technologies for denitrification, aeration and disinfection. The project presents a model for Maryland’s 66 largest wastewater treatment plants and possibly procurement of municipal facilities elsewhere facing increasingly stringent regulatory changes.
WRT has been contracted for 20 years to remove the contaminant from a well that provides drinking water to some 12,000 people in Pewaukee, located 20 miles west of Milwaukee. The treatment system, capable of processing 183,000 gallons of water a day, will lower the amount of radium in the water to a level below the U.S. Environmental Protection Agency’s (EPA) requirements, ensuring that the city has safe drinking water.
In 2010, Shelby County Water Services (SCWS) was planning for the future. With new regulations on the horizon, SCWS determined that the Talladega/Shelby water treatment plant in Shelby County, AL, needed more effective removal of disinfection byproducts (DBPs). Specifically, the treatment plant needed help complying with the U.S. EPA’s new Stage 2 Disinfection Byproduct Rule (DBPR).
Over the past two years, no groundwater issue has perhaps received as much community focus and attention as polyfluoroalkyl and perfluoroalkyl substances like PFOA and PFOS, often referred to as perflourinated compounds (PFCs). The U.S. EPA issued a health advisory, limiting the amount of these compounds to 70 parts/trillion which kicked off a nationwide evaluation of local water sources.
Do you think mobile POS is just hype? Stephen Bergeron VP of global marketing at APG Cash Drawer compiled a strong argument to the contrary in his presentation “Mobility and Cash Transactions: Emerging Technology In Retail” at RSPA’s RetailNOW 2013 Aug. 4-7, 2013, in Las Vegas.
The U.S. EPA sets national ambient air quality and greenhouse gas emission standards to ensure public health. Thermal mass flow meters deliver a direct reading of mass flow rate of natural gas and other fuel gases — without temperature and pressure compensation — and provide a simple, reliable and cost-effective method for tracking and reporting fuel consumption.
In the purification of monoclonal antibodies, the separation of monomers from product-related impurities is a major challenge. Here, we highlight the importance of screening various media.
